We do not build the tree CFG with multiple entry points in mind. So,
ENTRY_BLOCK_PTR always has exactly one successor: basic block 0.
I'm not even sure that multiple entry points are supported by the RTL
optimizers. I seem to remember discussions about that in the lists or
IRC, but my memory is hazy.
Yes, it's a bug :)
